Operating System Windows 7

Test Program Burnin Test Graphic Controller Display scrolling “Hwin” pattern with respective resolution Audio Controller Play 1kHz audio signal LAN Controller Data transfer to host PC Serial Port Read/Write operation to USB2.0 storage media. Parallel Ports Sent “H” (Arial 10) to printer Interface Controller Read/Write operation to hard disk The other peripheral devices were driven and operated in turn during all testing.

2.5. Test Procedure The EUT (within PC system) was placed on table which was above the ground by 80cm and PC System’s power cord was connected to the power mains through an Artificial Mains Network (A.M.N.). The other peripheral devices power cords were connected to the power mains through a line impedance stabilization network (L.I.S.N.). This provided a 50 ohm coupling impedance for the measuring equipment. (Please refer to the block diagram of the test setup and photographs.) Both sides of A.C. line were checked for maximum conducted interference. In order to find the maximum emission, the relative positions of equipment and all of the interface cables were changed according to ANSI C63.4-2009 during conducted measurement. The bandwidth of the R&S Test Receiver ESCS30 was set at 9kHz. The frequency range from 0.15MHz to 30MHz was pre-scanned with a peak detector. All the final readings from Test Receiver were measured with the Quasi-Peak detector and Average detector. (Remark: If the Average limit is met when using a Quasi-Peak detector, the Average detector is unnecessary)

3.3. Radiation Emission Limit (FCC§15.109/CISPR 22/ICES-003, Class B) All emanations from a class B computing devices or system, including any network of conductors and apparatus connected thereto, shall not exceed the level of field strengths specified below:

FREQUENCY DISTANCE FIELD STRENGTHS LIMITS (MHz) (Meters) (dBμV/m)

30 ~ 230 10 30 230 ~ 1000 10 37 Above 1000 3 74.0 (Peak) Above 1000 3 54.0 (Average)

Note: (1) The tighter limit applies at the edge between two frequency bands. (2) Distance refers to the distance in meters between the measuring

instrument antenna and the closed point of any part of the E.U.T. (3) There is no over 1GHz limits in CISPR 22/1997 standard. Therefore, a

FCC limit is used based on CFR 47 Part 15.35 (b) and Part 15.109 (a)(g). The 3m limit apply relation: L2 = L1(d1/d2)

(4) The system under test shall not exceed the radiated emission limits specified in Section 15.109 of this part by more than 6 dB.

3.4. Operating Condition of EUT Same as conducted measurement which is listed in 2.4., except the test set up replaced by section 3.2.

3.5. Test Procedure

3.5.1. For Frequency Range was 30MHz-1000MHz which measurement distance was 10m at Open Area Test Site: The EUT and its simulators were placed on a turn table which was 0.8 meter above ground. The turn table rotated 360 degrees to determine the position of the maximum emission level. EUT was set to 10 meters away from the receiving antenna which was mounted on an antenna tower. The antenna could be moved up and down between 1 meter and 4 meters to find out the maximum emission level. Bilog Antennas were used as receiving antenna. Both horizontal and vertical polarizations of the antenna were set on measurement. In order to find the maximum emission, all of the interface cables were manipulated according to ANSI C63.4-2009 on radiated measurement. The bandwidth of the R&S Test Receiver ESCI was set at 120kHz. The frequency range from 30MHz to 1000MHz was pre-scanned with Peak detector and all the final readings of measurement were with Quasi-Peak detector.

3.5.2. For Frequency Range was Above 1GHz which measurement distance was 3m at No.2 Semi-Anechoic Chamber: The EUT and its simulators were placed on a turn table which was 0.8 meter above ground. The portion of the test volume that was obstructed by absorber placed on the floor (30cm maximum). The turn table rotated 360 degrees to determine the position of the maximum emission level. EUT was set to 3 meters away from the receiving antenna which was mounted on an antenna tower. The antenna could be moved up and down between 1 meter and 4 meters to find out the maximum emission level. A calibrated Horn Antenna was used as a receiving antenna. Both horizontal and vertical polarization of the antenna were set on measurement, and both average and peak emission level were recorded form spectrum analyzer. In order to find the maximum emission level, all the interface cables were manipulated according to ANSI C63.4-2009 on radiated measurement. The resolution bandwidth of Agilent Spectrum Analyzer N9010A-526 was set at 1MHz The frequency range from Above 1GHz was checked with peak and average detector.
